Boards now connect like real lumber: B's end butts flush against A's surface,
offset from A's centerline by A's cross-section half-extent in B's approach
direction (width/thickness, whichever B faces). Previously B's center landed on
A's centerline, so boards interpenetrated and shared centerlines.
- Added Part.local_frame() (length/width/thickness world axes via composed
rotation matrices, matching geometry/viewer).
- join() computes the surface-contact offset; handles perpendicular T/L joints
and vertical legs (leg base butts the rail face).
- Tests: butt joint meets surface not centerline; example sentence updated;
vertical-leg join still correct. 45 passing.
Default alignment is B centered on A at the attach point. Not yet: joinery cuts
and flush-outer-face alignment options.

Viewport (woodshop-view): part labels (id/name), dimensioned floor grid in
inches, parallel-projection isometric default, selection highlight, quieter VTK.
Named projects: woodshop save/open/projects (slugified names under
~/.local/share/woodshop/projects/); wood-save/open/projects tools.
Driver: concise spoken summaries (verb+count roll-up so "build a table" speaks
one short line, not 12; queries/clarifications spoken verbatim); per-utterance
errors no longer kill the session; auto-discovers all wood-* tools.
Docs: real README and CLAUDE.md (architecture, full command set, limitations).
17 wood-* tools. 41 tests passing.
Verified end-to-end: "build a coffee table" and "make a bookshelf side frame"
each produce correct multi-board models with cut lists and STEP/STL export.
